Povezanost upalnih parametara i infekcija krvi uzrokovanih multirezistentnim Gram negativnim bakterijama kod COVID-19 pozitivnih bolesnika lijeÄenih u jedinici intenzivnog lijeÄenja ā retrospektivna studija jednog centra
Objectives: During the COVID-19 pandemics we have seen in critically ill COVID-19 patients treated in the intensive care unit the parallel outbreak of multidrug resistant Gram-negative bacteria bloodstream infections, mainly Acinetobacter baumannii and Klebsiella pneumoniae. Methods: We conducted a retrospective cohort single-center study. The aim was to investigate the incidence, etiology and impact of intensive care unit bloodstream infections in COVID-19 patients admitted to the COVID-19 intensive care unit with a known burden of multidrug resistance and to evaluate the possibility that inflammatory parameters levels measured at two different time points of treatment can early predict multidrug resistant Gram-negative bacteria bloodstream infections and enable timely beginning of bacterial targeted antimicrobial therapy. Results: Our study confirmed that procalcitonin values of 2,46 mcg/L and neutrophil/lymphocyte ratio of 28,9 could be a reliable indicators for high risk stratification of multidrug resistant Gram-negative bacterial infection origin in critically ill COVID-19 patients (Mann Whitney U test, P=0,02). Conclusion: Monitoring dynamic shift of inflammatory parameters in critically ill COVID-19 patients could reliably help clinician to recognize the multidrug resistant Gram-negative bacteria bloodstream infections and start with the antimicrobial therapy in a timely manner.Cilj istraživanja: Tijekom COVID-19 pandemije uoÄili smo kod kritiÄno bolesnih COVID-19 pozitivnih bolesnika lijeÄenih na odjelu intenzivne njege paralelno izbijanje infekcija krvi uzrokovanih multirezistentnim Gram negativnim bakterijama, uglavnom Acinetobacter baumannii i Klebsiella pneumoniae. U praksi rezultati mikrobioloÅ”ke potvrde infekcija krvi zavrÅ”eni su s odreÄenom vremenskom odgodom. Stoga primarni cilj istraživanja
bio je odrediti povezanost upalnih parametara (leukociti, limfociti, neutrofili, omjer neutrofila i limfocita, C-reaktivni protein, prokalcitonin) mjerenih u dvije razliÄite vremenske toÄke (dan prijema u jedinicu intenzivnog lijeÄenja i dan nastanka infekcija krvi potvrÄenih pozitivnim hemokulturama) i nastanka infekcija krvi uzrokovanih multirezistentnim Gram negativnim. Sekundarni ciljevi istraživanja bili su istražiti uÄestalost, etiologiju i utjecaj
infekcija krvi uzrokovanih multirezistentnim Gram negativnim bakterijama na ishod lijeÄenja COVID-19 pozitivnih bolesnika. Materijali i metode: Proveli smo retrospektivno kohortno istraživanje u KliniÄkoj bolnici Dubrava na intenzivistiÄkom odjelu COVID-19 pozitivnih bolesnika u vremenskom period od 31. listopada 2020. godine do 31. ožujka 2021. godine. U istraživanju je sudjelovalo 166 COVID-19 pozitivnih bolesnika koji su zadovoljili kriterije
ukljuÄenja u istraživanje. 122 COVID-19 bolesnika imali su mikrobioloÅ”ki potvrÄenu infekciju krvi uzrokovanu multirezistentnim Gram negativnim bakterijama. Kontrolna gupa imala je 44 COVID-19 bolesnika koji nisu razvili infekciju krvi. Svi podaci bolesnika skupljali su se iz povijesti bolesti i elektroniÄke baze podataka. Rezultati: NaÅ”a studija potvrdila je cut-off vrijednosti upalnih parametara prokalcitonina od 2,46 mcg/L i omjer neutrofila/limfocita od 28,9 kao pouzdane pokazatelje stratifikacije visoko riziÄnih COVID-19 bolesnika za nastanak infekcije krvi uzrokovane multirezistentnim Gram negativnim bakterijama, Acinetobacter baumannii i Klebsiella pneumoniae (Mann Whitney U test, P=0,02). ZakljuÄak: DinamiÄki monitoring upalnih parametara sa cut-off vrijednostima proklacitonina i omjera neutrofila i limfocita u razliÄitim vremenskim intervalima u kritiÄno bolesnih COVID-19 pozitivnih bolesnika pouzdani je pokazatelj visokog rizika nastanka infekcija krvi uzrokovanih multirezistentnim Gram negativnim bakterijama koji u kliniÄkoj praksi omoguÄuje pravovremeno uvoÄenje ciljane antimikrobne terapije prije dospijeÄa mikrobioloÅ”ke potvrde
Bacterial superinfections in critically ill COVID-19 patients ā experiences from University Hospital Dubrava tertiary COVID-19 center
Cilj istraživanja: Utvrditi incidenciju najÄeÅ”Äih bakterijskih superinfekcija, distribuciju uzroÄnika ovisno o sijelu infekcije, demografske podatke, relevantne laboratorijske i kliniÄke parametre te ishode lijeÄenja kritiÄno oboljelih bolesnika lijeÄenih u tercijarnom regionalnom centru specijaliziranom za lijeÄenje COVID-19 bolesnika PRIC KB Dubrava. Ispitanici i metode: Provedeno je retrospektivno opservacijsko ispitivanje te su podaci skupljeni pregledom povijesti bolesti u bolniÄkom informacijskom sustavu (BIS, In2, Zagreb) pacijenata lijeÄenih u jedinicama intenzivne medicine PRIC-IC KB Dubrava tijekom razdoblja od 01. ožujka 2020. do 01. veljaÄe 2021. Skupljeni podaci analizirani su u statistiÄkom programskom paketu jamovi. Rezultati: Od ukupno 692 pacijenta, 383 je razvilo bakterijsku ili gljiviÄnu superinfekciju. Njih 305 je razvilo pneumoniju, 133 bakterijemiju a 120 urinarnu infekciju. 66,3% pacijenata bilo je muÅ”kog spola, te su ÄeÅ”Äe primani sa bolniÄkih odjela i JIM-ova drugih bolnica. Od 305 pacijenata sa pneumonijom 295 je bilo mehaniÄki ventilirano te je razvilo VAP. Kod pacijenata koji nisu razvili bakterijemiju primjeÄen je porat omjera neutrofili leukociti, te limfopenija i pad vrijednosti CRP-a. Urinarna infekcija ÄeÅ”Äa je kod žena. U sve tri skupine, pacijenti su imali produljen period boravka u JIM-u i u bolnici. ZakljuÄci: Incidencija bakterijskih superinfekcija u kritiÄno oboljelih COVID-19 pacijenata vrlo je visoka i iznosi 55,3%. NajÄeÅ”Äe bakterijske superinfekcije su VAP, bakterijemija i urinarna infekcija. NajÄeÅ”Äi uzroÄni patogeni su MDR bakterije. Pacijenti sa sekundarnom infekcijom imaju dulji period boravka u JIM. PoveÄanje omjera neutrofili / limfociti i progresija limfopenije povezane su sa nepovoljnim kliniÄkim ishodima.Goal: To determine incidence of bacterial superinfections, causative pathogens demographic data, relevant laboratory parameters and outcomes in critically ill COVID-19 patients treated in primary respiratory intensivist center (PRIC) UH Dubrava. Patients and methods: In this retrospective observational study, clinical and laboratory data of 692 critically ill patients treated in PRIC UH Dubrava between March 1st 2020. and February 1st
2021. was collected using the hospital information system software (BIS) and statistical analysis was performed using the jamovi statistical package. Results: Out of 692 patients admitted to the ICU, 383 acquired bacterial or fungal superinfections. 305 acquired pneumonia, 133 bloodstream infections and 120 urinary infections. 66.3% of patients were males, and bacterial superinfections were more common in patients admitted from hospital wards or external ICUs. Out of 305 patients with pneumonia, 295 were receiving mechanical ventilation and satisfied the criteria for ventilator associated pneumonia. Patients with bloodstream infections maintained elevated neutrophil lymphocyte ratio, lymphopenia and elevated CRP levels on day 7 compared to those without BSI. Urinary infections were more common in females, and did not have an effect on outcomes. All patients that developed superinfections had prolonged ICU and hospital stay. Conclusion: Incidence of bacterial superinfections in critically ill COVID-19 patients is 55.3%. Most common infections are ventilator associated pneumonia, bloodstream infections and urinary infections. Most common pathogens are multi-drug resistant pathogens. Patients with bacterial superinfections have longer ICU and hospital stay, and in these patients, persistent elevation of NLR ratio and worsening of lymphopenia are characteristic for patients with worse outcomes

Distribution of Pathogens and Predictive Values of Biomarkers of Inflammatory Response at ICU Admission on Outcomes of Critically Ill COVID-19 Patients with Bacterial SuperinfectionsāObservations from National COVID-19 Hospital in Croatia
Background: Superinfections contribute to mortality and length of stay in critically ill COVID-19 patients. The aim of this study was to determine the incidence and pathogen distribution of bacterial and fungal superinfections of the lower respiratory tract (LRTI), urinary tract (UTI) and bloodstream (BSI) and to determine the predictive value of biomarkers of inflammatory response on their ICU survival rates. Methods: A retrospective observational study that included critically ill COVID-19 patients treated during an 11-month period in a Croatian national COVID-19 hospital was performed. Clinical and diagnostic data were analyzed according to the origin of superinfection, and multivariate regression analysis was performed to determine the predictive values of biomarkers of inflammation on their survival rates. Results: 55.3% critically ill COVID-19 patients developed bacterial or fungal superinfections, and LRTI were most common, followed by BSI and UTI. Multidrug-resistant pathogens were the most common causes of LRTI and BSI, while Enterococcus faecalis was the most common pathogen causing UTI. Serum ferritin and neutrophil count were associated with decreased chances of survival in patients with LRTI, and patients with multidrug-resistant isolates had significantly higher mortality rates, coupled with longer ICU stays. Conclusion: The incidence of superinfections in critically ill COVID-19 patients was 55.3%, and multidrug-resistant pathogens were dominant. Elevated ferritin levels and neutrophilia at ICU admission were associated with increased ICU mortality in patients with positive LRTI
